View OriginalTransthoracic echocardiogram (echo)
This picture shows a person getting an echocardiogram (or "echo"). To do an echo, a doctor or nurse puts some gel on a persons chest. He or she presses a thick wand (called a "transducer") against the chest and moves it around. An echo uses sound waves to create images of the heart that appear on a computer screen. A test called an ECG is done during an echo. For an ECG, patches (called "electrodes") are stuck to a person's chest. Wires run from the patches to a machine that records the electrical activity of the heart.
